These RTS SFI Black Premium Series Flexplate's are made for high performance street car drivetrains. RTS flexplate made specifically for our Holden Chevrolet LS and other popular performance cars. Each flexplate is dynamically balanced to eliminate potentially damaging vibrations and electro-coated black for protection from the elements.

Flexplates are .035" thicker than stock and the starter ring is welded to both sides of the flexplate for additional strength. Constructed from a high tensile strength material, these flexplates resist elongation and cracking. All 153-tooth flexplates have dual GM bolt patterns and are sized for stock 3/8" mounting bolts. They can be easily drilled for 7/16" diameter high performance torque converter applications and are SFI 29.1 approved.

Fits all internally balanced Holden Chev V8 engines, SFI approved.
